SYNOPSIS
.In ctype.h int isprint "int c"
DESCRIPTION
The isprint function tests for any printing character including space (" "). For single C char s locales (see multibyte(3)) the value of the argument is representable as an unsigned char or the value of EOF. In the ASCII character set, this includes the following characters (with their numeric values shown in octal): "040 sp 041 ! 042 " "043 # 044 $" "045 % 046 & 047 050 ( 051 )" "052 * 053 + 054 , 055 - 056 ." "057 / 060 0 061 1 062 2 063 3" "064 4 065 5 066 6 067 7 070 8" "071 9 072 : 073 ; 074 < 075 =" "076 > 077 ? 100 @ 101 A 102 B" "103 C 104 D 105 E 106 F 107 G" "110 H 111 I 112 J 113 K 114 L" "115 M 116 N 117 O 120 P 121 Q" "122 R 123 S 124 T 125 U 126 V" "127 W 130 X 131 Y 132 Z 133 [" "134 \ 135 ] 136 ^ 137 _ 140 " "141 a 142 b 143 c 144 d 145 e" "146 f 147 g 150 h 151 i 152 j" "153 k 154 l 155 m 156 n 157 o" "160 p 161 q 162 r 163 s 164 t" "165 u 166 v 167 w 170 x 171 y" "172 z 173 { 174 | 175 } 176 ~" | | | |
RETURN VALUES
The isprint function returns zero if the character tests false and returns non-zero if the character tests true.
COMPATIBILITY
The BSD 4.4 extension of accepting arguments outside of the range of the .Vt "unsigned char" type in locales with large character sets is considered obsolete and may not be supported in future releases. The iswprint function should be used instead.
